Jonas, 26, and the Quantico star, 36, are expected to wed soon.
They’ve been sharing photos on Instagram indicating that they’re currently in Mumbai, and Jonas’ older brother, Joe Jonas, 29, and his fiancée, Game of Thrones actress Sophie Turner, 22, recently joined the festivities.
Chopra’s friendship with the Duchess of Sussex dates back to 2016, when the two met at the ELLE Women in Television dinner.
“We bonded as actors,” Chopra told PEOPLE of their friendship in September 2017. “We just became friends, like two girls would.”
“I think friendships depend on people individually and how personal your relationship is,” she reflected back in July.
“You can have work friendships, those are different. But when you have real friendships, like ours, it doesn’t matter what people look at you as or where your world goes, you sort of just, stay friends. And I think that’s what we’re like.”
